Trajectory, an AI startup that raised 59.985 billion won, valued at 399.9 billion won

AI startup Trajectory raised $45 million (about ₩59.985 billion) in a Series A round led by Sequoia Capital, with participation from Nvidia, Bessemer Venture Partners, and Bain Capital Ventures, valuing the company at $300 million (about ₩399.9 billion). Founded roughly a year ago by three Stanford alumni with backgrounds at Google DeepMind and Apple, the company has 18 employees. Trajectory is developing AI models that can learn from mistakes without additional training, targeting enterprise applications in specialized fields like law and finance where current models fall short. The round signals continued strong investor appetite for early-stage AI infrastructure plays, with Nvidia's participation notable given its strategic positioning across the AI stack. Watch for how Trajectory deploys the new capital against competitors pursuing similar self-improving model approaches, and whether the valuation holds up as enterprise AI adoption matures.
